  • Process for the production of aromatic anhydrides and aromatic esters with superior color properties
    Patent number: 5101050
    Abstract: A process for the production of aromatic esters or aromatic anhydrides with improved color properties is disclosed. This process comprises treating the aromatic ester or aromatic anhydride with an activated boric acid followed by fractionation.
    Type: Grant

  • Shale oil stabilization with a hydrogen donor quench and a hydrogen transfer catalyst
    Patent number: 4536277
    Abstract: A process is provided to produce and stabilize shale oil. In the process, raw oil shale is retorted with heat carrier material to liberate an effluent product stream comprising hydrocarbons and entrained particulates of oil shale dust. In order to minimize polymerization of the product stream and agglomerate the shale dust, the product stream is stabilized with a hydrogen donor quench in the presence of a hydrogen transfer catalyst upon exiting the retort. The quenched stream is subsequently purged of catalyst, dedusted, and upgraded.
    Type: Grant

    Date of Patent: August 20, 1985
    Assignee: Standard Oil Company (Indiana)
    Inventors: Thomas M. O'Grady, David F. Tatterson, Ronald Coates
  • Shale oil stabilization with a hydrogen donor quench
    Patent number: 4536278
    Abstract: A process is provided to produce and stabilize shale oil. In the process, raw oil shale is retorted with heat carrier material to liberate an effluent product stream comprising hydrocarbons and entrained particulates of oil shale dust. In order to minimize polymerization of the product stream and enhance agglomeration of the shale dust, the product stream is stabilized with a hydrogen donor quench upon exiting the retort. The quenched stream is subsequently dedusted and upgraded.

  • Semi-regenerative reforming process providing continuous hydrogen production
    Patent number: 4208397
    Abstract: The process comprises passing a hydrocarbon stream under reforming conditions through each of the reactors of the unit; when the catalyst in all of the reactors in the unit except the lead reactor has become deactivated to such an extent that the catalyst in all of the reactors other than the lead reactor must be regenerated, discontinuing the flow of the hydrocarbon stream through all of the reactors in said unit other than the lead reactor while continuing to pass the hydrocarbon stream through the lead reactor; regenerating the beds of catalyst in each of the reactors of said unit other than the lead reactor to remove the carbonaceous deposits from the catalyst in such beds and to restore at least partially the activity of the catalyst while continuing to pass the hydrocarbon stream through the lead reactor under reforming conditions; resuming the flow of the hydrocarbon stream through all of the reactors in the unit; and repeating all of the aforesaid steps until the catalyst in the lead reactor has becom
